Design features:

    The connection between stem nut and hand wheel depends on the claw type clutch, the micro motor inside of the valve is remote-controlled by means of the electronic remote controller, which enable the claw type clutch slips up and down so as to control the on/off between stem nut and hand wheel. Under the condition of connection, turn the hand wheel to perform the open/close of the valve, and under the condition of disconnection, the valve cannot be open or closed even if the hand wheel is rotated, so the valve takes the anti-burglar function.
